Abstract: ABSTRACT     There are disclosed a method and a machine for constructing a shaft having a substantially circular cross-section.  According to the present invention, the shaft having a shotcrete formed on a peripheral wall thereof can be easily constructed.  The shotcrete can be promptly formed on the peripheral wall by spraying concrete toward the wall above the water level of the water W before the wall is broken.  Also, muck excavated from a working face of the shaft can be efficiently conveyed therefrom to outside of the shaft even if the shaft has a depth of more than hundreds meters.

Abstract: ELECTRICALLY OPERATED DISC BRAKE WITH BACK-OFF PROTECTOR The electrically operated disc brake (10, 110, 310, 410) may be operated by either hydraulic pressure and an electric motor or operated solely by means of an electric motor. The electric motor (40, 340, 440) drives a sun gear (52, 352, 452) of a planetary gear assembly (50, 150, 350, 450). The planetary gear assembly (50, 150, 350, 450) includes a fixed ring gear (70, 370, 470) and a rotatable ring gear (80, 180, 380, 480), the rotatable ring gear (80, 180, 380, 480) having fewer teeth than the fixed ring gear (70, 370, 470) so that rotation of the planetary gears (54, 56, 58) effects a slower rate of rotation of the rotatable ring gear (80, 180, 380, 480). The rotatable ring gear (80, 180, 380, 480) engages a screw (88, 188, 388, 488) which is connected with the piston (30, 130, 330, 430). The piston (30, 330, 430) may be displaced by hydraulic fluid for a service application and the electric motor (40, 340, 440) utilized for a parking application. Alternatively, the piston (130) may be displaced by the electric motor (40) for both service and parking brake applications.

Abstract: A travel speed limiting control system for lift trucks, par-ticularly of the "orderpicker" type, having an extendible mast, is disclosed.  The truck travel speed which the operator can command is limited by factors including load weight, load elevation, heading angle and direction of truck travel (forward or reverse).  Optional-ly, other factors may be involved, such as lateral tilt and load moment.   An algorithm including the desired  input  factors  is continually processed by an on-board microcomputer to provide an instantaneous  speed  limit signal.   In addition to  its normal operating mode, the microcomputer is also arranged to operate in a "learn" mode, whereby it runs through the ranges of various input signals and develops a set of stored values which indicate the allowable ranges of the inputs, as well as offset or bias values which compensate for manufacturing tolerances occurring in the components of the system.

Granted: 1994-07-05
Abstract: ABSTRACT          A decoding system according to the invention dispenses with an externally arranged frame synchronizer by incorporating the function of the frame synchronizer into the decoding system itself.  The decoding system decodes coded video signals coded by a predetermined coding algorithm, and supplies decoded video signals.  It includes a buffer memory for temporarily storing the coded video signals.  A frame sync signal detector detects frame sync signals out of the video signals temporarily stored in the buffer memory and generates sync detection signals.  A reference sync signal detector detects reference sync signals provided from outside and generates reference sync detection signals.  A decoder is responsive to the frame sync and reference sync detection signals to read the video signals out of the buffer memory and decodes the video signals.

Abstract: PHASE SHIFTED FEEDBACK ELECTROMETER           Abstract of the Disclosure A detector for airborne alpha radiation includes a ion pulse collecting chamber connected to a phase shifted, 100% negative feedback electrometer circuit.  The ion pulse chamber includes a probe surrounded by an 80% open grid, with the spacing between the probe and the grid providing no greater than about 50 ms transit time before collection and having a capacitance of less than 1 pf.  The field strength between the probe and the grid is less than 10 V/cm. The ion pulse chamber is contained within a vented cabinet.  If it is desired to count only radon, a negative potential with respect to the grid may be applied to the cabinet to collect positvely charged free ions.  Alternatively, the cabinet wall can be made positive with respect to the grid to create a potential-well at or near the grid to provide an enhanced daughter detection mode.  If the cabinet wall and the grid are the same potential, both radon and daughter alpha radiation are detected.

Abstract: A television picture transmission system using conditional replenishment employs a scanning rate at the transmitter which differs (for asynchronous operation, slightly; or for operation between systems using different standards, considerably) from the scanning standard at the the receiver. The frame rate conversion is effected by the updating loops at the transmitter or receiver by, respectively, periodically stopping the coding loop for a field or frame so that no data is produced to produce a lower frame rate or periodically repeating a field or frame in the loop without adding any updating data so as to produce a higher frame rate. Resulting variations in data rate are accommodated by utilising the buffering inherent in conditional replenishment systems. The jerkiness of motion in the received picture resulting from stopping the loop or repeating a field or frame can be reduced by the use of temporal interpolation in the generation of the updating data to anticipate the stopping or repeating of a field or frame, whilst conversion of the number of lines per frame can be effected by spatial interpolation using a transversal filter.
